Abstract
The utility model relates to an isolating switch operating mechanism with a simple structure. The operating mechanism adopts harmonic gear motor with double output shafts, wherein the output shaft at one terminal of the harmonic gear motor is used for driving isolating switch, and the output shaft at non-drive terminal of the harmonic gear motor is sequentially provided with position detection unit auxiliary contact (3) and position indicator (6). The non-drive terminal is also used for manual operation and provided with manual locking switch (8) on the housing (4) of the end cover. When taking off transparent manual protective hood (5), it is not allowed to turn the isolating switch through rocking handle until the locking switch cuts off the power supply of the harmonic gear motor.
Description
Affiliated technical field
The utility model relates to a kind of operating mechanism that is installed on the high voltage isolator, and this operating mechanism drives the separating brake and the combined floodgate of isolating switch.
Background technology
The action of high voltage isolator is finished by operating mechanism, and operating mechanism drives the separating brake and the combined floodgate of isolating switch.The operating mechanism of present used high voltage isolator is a split-type structural, motor is exported through multi-stage speed-reducing again, detection for the position of the switch is to output in the auxiliary contact rotating shaft through drag link mechanism, the operating mechanism volume of traditional structure is huge on the isolating switch, mechanism's complexity, the reliability of operating mechanism is relatively poor.
Summary of the invention
In order to overcome the deficiency of existing isolator operating mechanism, the utility model proposes a kind of simple in structure, the new operating mechanism structure solution that volume is less.
The utility model technical scheme that is adopted of dealing with problems is: operating mechanism adopts the harmonic gear decelerator of two shafts, and one brings out axle and is used to drive isolating switch, and the anti-drive end shaft is placement position detection unit auxiliary contact and position indication successively.The anti-drive end shaft also is used for manual operation, and places the manual locking switch on the end cap shell, and when taking off transparent manual protective cover, locking switch disconnects the power supply of harmonic gear decelerator, can be to rotate isolating switch by rocking handle.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structure chart 1 of the present utility model.
Structure side view of the present utility model when Fig. 2 is no end cap outer cover, promptly inner member is placed figure.
Structure side view of the present utility model during Fig. 3.
Among Fig. 1
1. the harmonic gear decelerator of two shafts, the 2. cam used of position probing, 3. auxiliary contact, 4. end cap outer cover, 5. transparent manual protective cover, 6. position indication, 7. sensitive switch, 8. locking switch.
Fig. 2 is the end view during no end cap outer cover among Fig. 1,9. connector sockets among Fig. 2,11. control relays.
Structure side view of the present utility model during Fig. 3.
Embodiment
After the cam 2 that position probing is used assembles, regulate the position of sensitive switch, can regulate the rotational angle of operating mechanism output.
Assembly sequency is to assemble end cap outer cover 4 earlier, and the installation site indication 6 again, and transparent manual protective cover 5 is installed at last.Air brushing position sign on the end cap outer cover, transparent manual protective cover transparent material manufacturing can be seen the rotating shaft position indication.
Locking switch 8 is installed on the end cap outer cover, install transparent manual protective cover 5 after, the ledge on the transparent manual protective cover touches locking switch 8, locking switch closure.When taking off transparent manual protective cover, locking switch disconnects.
After installing transparent manual protective cover 5, stopped the enforcement of manual function.When taking off transparent manual protective cover, locking switch disconnects, 1 outage of harmonic gear decelerator, and this moment can be with manual rocking handle rotating shaft, the realization manual operation, roller end should be hexagon or other polygons, is convenient to manual rocking handle carry-over moment.
Control relay 11 is rotatings of control motor, realizes the limited angle rotation.Cam 2 structures shape that the anglec of rotation is used by the position and the position probing of sensitive switch.The sensitive switch position is adjustable.
Claims (2)
1. the operating mechanism of an isolating switch, its architectural feature is: the anti-drive end at the harmonic gear decelerator of two shafts is provided with position detection unit, auxiliary contact and position indication.
2. isolator operating mechanism as claimed in claim 1, its architectural feature also is: the end cap outer cover is provided with manual locking switch and transparent shield.
